No tears here: Audrina Patridge looked to be in great spirits as she modeled a bikini in Miami on Saturday, just weeks after splitting from Corey Bohan

The MTV star smiled as she took a dip in the Atlantic Ocean with her sunglasses and long chandelier earrings still on.The looker appeared to be with at least two female friends as they sunbathed until sunset.

Nowhere in sight was Australian BMXer Corey or any other potential dates. UsWeekly first reported the Patridge and Bohan had gone their separate ways after a long on and off relationship that included at least two breaks.

The brunette pinup and Corey began dating in 2009 after Audrina broke up with MTV's Justin Brescia. 'She's single right now,' Us explained. She had often been seen with him at splashy events in Las Vegas.

The two looked to be serious so the split came as a surprise. Ever since their last break in March of 2011, it seemed they were stronger than ever.

'We've been off and on for almost five years,' Audrina told UsWeekly last July, 'but we've been solid.'

The brunette gushed to the site at the same event that he was the love of her life and the two had 'talked about ' getting married, but apparently that is no longer the case.

In late July when she attended the Young Hollywood Awards, the pretty reality star posted a quote by Andre Malraux on her Instagram account saying, 'Man is not what he thinks he is, he is what he hides,' perhaps giving her fans some insight into the reason for the breakup.

Audrina also revealed how she never really felt very secure when she dated other guys including Ryan Cabrera, Mark Salling and Chris Pine.

'With other guys in the past I dated, I never felt safe,' she told the publication.  'We'd go out and I felt like I had to defend them, and so with Corey I feel like I'm safe -- he's a guy's guy.
'He's not afraid to get dirty and that's what I like about him. He's not super metro.' But despite her feeling of security with Corey, sources say this break up is the real deal. 'I don't think they'll get back together this time,' the insider says.
